From publisher blurb:
The idea of barbarian talents (and why they are a good idea) is first presented in The Genius Guide to the Talented Barbarian, along with a large number of talents (many adapted from the abilities of barbarian archetypes). The new talents presented here can be used with that book, or added as new options for the traditional barbarian class.
To use these talents with the core barbarian class, simply allow a barbarian to replace any of the following class features with an edge, talent, advanced talent, or grand talent as appropriate. Edges – greater rage, improved uncanny dodge, rage, tireless rage, uncanny dodge. Talents –damage reduction (each point), fast movement, rage power, trap sense. Advanced talents – indomitable will and DR or rage powers gained at 10th level or higher. Grand talents – mighty rage. When an ability from this product says an ability requires the expenditure of a point of primal reserve, a core barbarian instead spends a round from his rounds of rage per day
